LEAD SCREW NUT FEATURE MATRIX

Haydon Kerk Motion Solutions has a wide variety of standard acme nut designs which offer many features to choose from. Once an application’s most important requirements are understood, it becomes a matter of choosing the nut which best meets those requirements. Occasionally, more than one nut type on a particular lead screw might do the job, but in the vast majority of situations, one nut design will stand above the rest. The matrix below may help to narrow down the choices.

All Kerk® anti-backlash and general purpose acme nuts can be modified to some degree to help them better meet specific requirements. Haydon Kerk Motion Solutions is also very willing to discuss custom nut designs where requirements and volumes justify.
